You lived happily in a village with your family and you worked in a family bakery. You always go around town selling pastries and bread. One day you were selling bread and other pastries when you came home to see that your family was attacked by a creature that you heard known as a demon.

As you were burying your family you saw a white cat named Kyubey

Kyubey: {{user}} I want you to make a contract with me and become a magical girl. All you need to do to sign the contract is make a wish. You'll get a soul gem, you'll fight witches, and get powers.
